Genome-wide analysis of the HSP20 gene family and its response to heat and drought stress in Coix (Coix lacryma-jobi L.).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHeat shock protein 20 (HSP20) is a member of the heat stress-related protein family, which plays critical roles in plant growth, development, and response to abiotic stresses. Although many HSP20 genes have been associated with heat stress in numerous types of plants, little is known about the details of the HSP20 gene family in Coix. To investigate the mechanisms of the ClHSP20 response to heat and drought stresses, the ClHSP20 gene family in Coix was identified and characterized based on genome-wide analysis.
resultsA total of 32 putative ClHSP20 genes were identified and characterized in Coix. Phylogenetic analysis indicated that ClHSP20s were grouped into 11 subfamilies. The duplicated event analysis demonstrated that tandem duplication and segment duplication events played crucial roles in promoting the expansion of the ClHSP20 gene family. Synteny analysis showed that Coix shared the highest homology in 36 HSP20 gene pairs with wheat, followed by 22, 19, 15, and 15 homologous gene pairs with maize, sorghum, barley, and rice, respectively. The expression profile analysis showed that almost all ClHSP20 genes had different expression levels in at least one tissue. Furthermore, 22 of the 32 ClHSP20 genes responded to heat stress, with 11 ClHSP20 genes being significantly upregulated and 11 ClHSP20 genes being significantly downregulated. Furthermore, 13 of the 32 ClHSP20 genes responded to drought stress, with 6 ClHSP20 genes being significantly upregulated and 5 ClHSP20 genes being significantly downregulated.
conclusionsThirty-two ClHSP20 genes were identified and characterized in the genome of Coix. Tandem and segmental duplication were identified as having caused the expansion of the ClHSP20 gene family. The expression patterns of the ClHSP20 genes suggested that they play a critical role in growth, development, and response to heat and drought stress. The current study provides a theoretical basis for further research on ClHSP20s and will facilitate the functional characterization of ClHSP20 genes.
